Category: Plant Care Tips

Every October it happens the same way. We go to bed in the 90s, a norther blows through around midnight, and by breakfast my phone is full of texts that all ask the same thing: “Do I need to bring my plants in?”

This year it came through on a Thursday night in the middle of October. One last 93-degree afternoon, a wall of north wind, and by the weekend we were looking at mornings in the 40s. After the summer we just had, it feels like winter showed up overnight.

It didn’t. For most of you the answer is no. Leave them out. Here’s how I actually make that call with my own plants and my clients’, and the handful of things a first cold front genuinely does call for.

#1 — The Number on the News Isn’t the Number on Your Porch

Austin’s official temperature comes from Camp Mabry, which sits in the middle of town and stays warmer than most of the metro on a cold night. Your plant doesn’t live at Camp Mabry. It lives on your porch, and where exactly on your porch matters more than people think.

A pot sitting out on open ground on a clear, calm night can run several degrees colder than the forecast, because it’s losing heat straight up to the sky. The same pot tucked under a porch roof and pushed against a brick or limestone wall can run several degrees warmer. The overhang stops that heat loss, and the wall gives back the warmth it soaked up all afternoon. That gap is often the whole difference between a plant that shrugs off a cold morning and one that sulks for a week.

And if you live out past the Y, in Dripping Springs, Wimberley, or anywhere in a Hill Country valley, knock a few more degrees off whatever the Austin forecast says. The Hill Country typically sees its first freeze around mid-November. Central Austin usually doesn’t get one until around the first of December. Same forecast on the TV, very different night in your yard.

So the first thing I do after a front like this isn’t bring anything inside. It’s push the pots together under the overhang, against a south or east wall, off the open patio. That one move buys more protection than most October mornings will take away.

#2 — Know Which Plants Actually Mind the 40s

Most of the tropicals people keep on Austin porches handle a night or two in the upper 40s just fine. Monsteras, pothos, most philodendrons, birds of paradise, rubber trees: a 47-degree morning on its way to a sunny 70-degree afternoon doesn’t bother them. They’ll slow down a little and that’s it.

The fussy ones are a different story. Calatheas, aglaonemas, crotons, alocasias and dieffenbachias start to complain in the upper 40s. You’ll see dull or curling leaves, maybe some dark spotting a few days later. Those are the ones I’d give the most sheltered spot you’ve got, and if you’re out in the Hill Country with a forecast low in the mid-40s, bringing just those few in for a night or two is reasonable. Not the whole porch. Just the divas.

The line that matters for everything is 40 degrees. Down in the low 40s and below, cold damage stops being cosmetic and turns into black, mushy stems you can’t undo. My rule, which I go into more in my guide to keeping tropicals outdoors in Austin: if the forecast shows the low 40s anywhere in the next 48 hours, plants come in the night before. Not the morning of.

How long the cold lasts matters too. An hour at 47 right before sunrise is nothing like a night that sits in the low 40s for ten hours. Most early fall fronts here give you the first kind.

#3 — This Week’s Real Problem Is the Wind and the Dry Air

Here’s what the first front actually brings that people don’t think about. It isn’t just cooler air. It’s a hard north wind, often gusting 30 or 40 miles an hour, and humidity that drops from summer’s swamp straight down into the 20s. After four months of sticky Gulf air, that’s the shock your plants are feeling right now. Not the temperature.

Big soft leaves take it worst. Birds of paradise, bananas and elephant ears will shred in a day of that wind. Tall plants in lightweight plastic nursery pots tip over, and I’ve seen more broken monstera stems from a porch tumble in October than from anything the cold did. Move the tall ones out of the wind, set them against something solid, or lay them on their side for a windy afternoon if that’s the only option.

Then check the soil. Nobody thinks about watering when it’s sweater weather, but a cool, sunny, windy day with 20-percent humidity pulls water out of a pot faster than you’d expect. Stick a finger in. If it’s dry a couple of inches down, water in the morning so the pot drains and warms up through the day. What you don’t want is to water in the evening right before a cold morning. Cold, soggy roots are how a harmless 45-degree night turns into rot.

#4 — Bring Them In Now and You’ll Want Them Back Out by Midweek

These first fronts don’t stick. That’s Austin in October. We drop into the 40s for a couple of mornings and then we’re right back in the 80s by the middle of the next week. The calendar says fall. The weather says maybe.

Haul everything inside now and here’s what happens. Your plants go from a breezy porch into a house where the AC kicks right back on the moment it warms up again. That sudden drop in light and humidity is what makes porch plants drop leaves the first week back indoors. Worse, any spider mites that were hitching a ride, held in check outside by humidity and the bugs that eat them, now have dry air and no predators. Two mites become two thousand in about ten days. I’ve written about what that looks like in my post on Austin houseplant pests.

Then the next warm spell comes and you carry them all back out, and you do it again with the next front. Every one of those moves is a shock. I’d rather move a plant once, at the right time.

There’s also something you give up by bringing them in early. October and the first half of November are some of the best growing weeks of the whole year here. Mild days, cool nights, decent light, no more scorching afternoons. A plant on the porch right now is in better conditions than it saw all summer. Let it have them.

#5 — Use This Weekend to Get Ready for the Real Move

So when do they actually come in? For most of Austin, that’s sometime in November, whenever the 48-hour forecast first shows the low 40s. Central Austin’s average first freeze is around December 1, the airport side of town runs a few days earlier, and the Hill Country gets there around mid-November. The earliest freeze ever recorded in Austin was October 26, 1924, so it’s not impossible this month, which is exactly why you watch the forecast instead of the calendar.

But a cool, dry, sunny weekend is the best weather you’ll get all year for the prep work, so this is when I’d start. Go plant by plant and look at the tops and undersides of the leaves in good light. Hose each one down hard, undersides included. Treat with insecticidal soap. Flush the soil and let it drain. If anything had a pest problem this summer, deal with it now, outside, where an overspray doesn’t matter.

Then walk your house and decide where each plant is going to live. Light changes fast this time of year. A spot that was bright in July can be dim by Thanksgiving because the sun is lower and coming in at a different angle. I explain exactly why in my post on what Austin’s winter light does to houseplants. Pick spots near the south and west windows, away from heating vents, and clear the floor space now.

Do all that this weekend and the actual move, whenever it comes, is a twenty-minute job instead of a panicked night with a flashlight and a forecast alert.

And If Your Plants Live Inside All Year

Good news: enjoy the break. Your AC is finally cycling less, which means the air in your house is less brutal than it’s been since May. If you’ve got the windows open to enjoy it, just keep plants out of the direct path of that dry north wind, and start easing off the watering as the days get shorter. Nothing else to do yet.

The time to think about cold for indoor plants is the first real freeze, when the air right against the window glass can sit twenty degrees colder than the rest of the room. That’s covered in my Austin freeze prep guide, and it’s worth a read before Thanksgiving.

Want a Hand With It?

If you’ve got a porch full of big tropicals and the thought of inspecting, treating and hauling every one of them inside sounds like a lost weekend, that’s something I do for clients through Keep Austin Watered. I do the pest treatment outside, move everything in, and find each plant a spot that’ll actually hold up through an Austin winter, away from the vents and in the light it needs. Text me a photo of your porch and I’ll tell you honestly whether you need me or just a free Saturday.

Every January I get the same call, usually from someone who did nothing wrong. The fiddle leaf that looked great all summer is dropping leaves. The pothos has gone pale and stopped growing. Nothing changed — same pot, same spot, same watering can, same schedule.

That’s the problem. Nothing changed.

Austin’s winter doesn’t announce itself the way a freeze does. It arrives as a slow shift in light that almost nobody notices until the plants have been telling them about it for six weeks. Here’s what’s actually happening, and why the room you know in August is a different room in December.

Problem #1: Your south window just became the best spot in the house

This is the one that surprises people, so let me give you the number. At noon on the summer solstice the sun sits about 83 degrees above the horizon in Austin — almost straight overhead. By the winter solstice it’s down to about 36 degrees. That’s a 47-degree drop.

What that means in your living room is more dramatic than it sounds. Run the geometry on an ordinary six-foot window and the noon sun reaches roughly eight inches into the room in June. In December it reaches about eight feet. Same window, same time of day, eleven times the reach.

So the south- and west-facing spots that cooked your plants all summer — the ones I’m forever telling people to pull back from — become the prime real estate of the year from about November through February. The light is lower, longer, and far gentler than the overhead glare of August. If you’ve got a plant that’s been sulking in a dim corner since spring, winter is when you move it toward the glass, not away from it.

The catch is that you have to move it back. Around March that same window starts climbing again, and the plant you rescued in December will scorch by May if you leave it there. I treat it as two moves a year, and I do them on the equinoxes because they’re easy to remember.

Problem #2: Four hours of daylight disappear and nobody adjusts the watering

Austin gets just under fourteen hours of daylight at midsummer and just over ten at the winter solstice. Roughly four hours a day, gone. Add the weaker angle and the gray stretches we get in January, and your plants are running on a fraction of the energy they had in July.

A plant photosynthesizing less is drinking less. Considerably less. But the watering can doesn’t know that, and most people are still on the schedule they built in the summer, when a pot could go bone dry in three days.

That is the single most common thing I find on a January rescue visit, and it isn’t neglect — it’s care, applied on the wrong calendar. Cold soil, weak light, no air movement, and water arriving every five days out of habit. The roots sit wet, they rot, and the part you can see doesn’t show it until the plant is well past the point where a change of routine would have fixed it.

A drought-stressed plant looks dramatic and gets noticed. A rotting one looks fine right up until it falls over.

So in November, stretch the interval. Don’t water on a schedule at all if you can help it — put a finger two inches into the soil and only water when it’s dry down there. For most of what people grow indoors here, the winter answer is less water, later than you think.

Problem #3: The heater does what the AC did, only drier

Everyone in Austin knows the AC dries a house out. Far fewer people clock that running the heat is harder on a plant, because forced-air heat pulls indoor humidity down further and does it while the plant is already stressed by low light.

The fix is mostly about placement, and it takes five minutes. Walk the house and look at where your registers actually point. A vent blowing across a plant for an entire winter will crisp the leaf edges on anything thin-leaved no matter how perfectly you water it — and then you’ll spend January treating a watering problem that was a heating-vent problem all along. Anything sitting in the path of one gets moved. Grouping plants together helps too; they hold a pocket of humidity around themselves, which costs nothing.

If the leaf tips are going brown and crisp rather than soft and yellow, that’s usually air, not soil — though in Austin it’s worth ruling out what’s coming out of the tap before you blame the furnace. I’ve written up what our water does to houseplants separately.

Problem #4: Winter is when people intervene, and it’s the worst month for it

Here’s the trap the other three set up. The plant looks bad, you want to help, so you do something — bigger pot, fresh soil, a round of fertilizer. All three are reasonable instincts and all three are wrong in January.

A plant in low light isn’t growing much, so it can’t push roots into fresh soil, and a bigger pot just means more wet medium sitting around roots that aren’t drinking. Fertilizer on a plant that isn’t actively growing burns roots that are already under stress. You end up adding a second problem to the one you were trying to solve.

If a plant genuinely needs a new pot, it can almost always wait until March — and when it is time, the soil you use here matters more than the pot. Through the winter, the useful interventions are the free ones: move it toward the light, water it less, and get it out of the path of a vent.

The ten-minute November reset

Once a year, usually the first week of November, I walk a client’s house and do the same four things. It takes about ten minutes and it prevents most of what I’d otherwise be called about in January.

Move the plants toward the south and west glass — the spots that were too hot in August are the good ones now. Check where the heating vents blow and move anything sitting in front of one. Stretch the watering interval and start checking the soil with a finger instead of the calendar. And stop feeding until you see new growth in spring.

That’s it. No products, no repotting, nothing to buy.

One more thing worth doing while you’re at it: anything within a few feet of an exterior window is in a colder microclimate than your thermostat suggests, which matters enormously the first time a hard freeze shows up. That’s a different job with a different checklist, and I’ve put it all in my Austin freeze guide.

If you’d rather not think about it

This is a lot of small seasonal judgment, and it’s most of what I actually do — the light moves, the watering changes, the vents get checked, and somebody notices the plant is drinking less before it becomes a problem instead of after. That’s the whole service: biweekly visits, watering matched to the season and to each plant rather than a blanket schedule, and someone who’s been reading Austin rooms for 25 years deciding where things should sit in December versus June.

If your collection is looking tired and you’re not sure whether it’s light, water, or the furnace, that’s a good thing to sort out now rather than in February. Book a free consult, or text me at (512) 829-1467.

Somebody texts me a photo of a packed car about once a week. In July it’s a cooler and two kids and the question is whether the monstera survives Port Aransas. In December it’s a suitcase in an Uber and the question is whether anything survives ten days in Ohio with the thermostat at 60.

People assume the summer trip is the dangerous one. After 25 years of doing this in Austin, I’d tell you the opposite. Summer kills plants faster, but winter kills more of them — because winter trips are longer, the failure is slower and harder to see coming, and there’s a specific Austin problem in December and January that doesn’t exist in August.

Here’s what’s actually happening in your house while you’re gone, in both seasons, and how to leave anyway.

Problem #1: In winter, the danger flips from drought to rot

The summer rule is simple — a warm empty house dries soil fast, and a pot that held moisture for a week with you home can go bone dry in three or four days. Everybody intuits that one, even if they don’t act on it.

Winter runs the other direction and almost nobody sees it coming. You drop the thermostat to 60 on the way out. The days are short and the light is weak. Your plants slow way down — they’re barely drinking. Meanwhile whoever you asked to check in is watering on the same schedule they’d use in July, because that’s the number you gave them. Cold soil, weak light, no air movement, and water arriving every five days. That’s not plant care, that’s a root rot protocol.

I get more January rescue calls than August ones, and the January plants are usually further gone. A drought-stressed plant looks terrible and gets noticed. A rotting one looks fine right up until it falls over.

Problem #2: Loading up on water before you leave has never worked

This is the move everybody makes — really soaking everything the night before, sometimes twice in the last two days. I understand the instinct completely, and it does nothing. You can’t bank water in a pot. The plant drinks at its own pace and the rest just sits there with nowhere to go.

In summer that gives you saturated roots in a warm, still house. In winter it’s worse: saturated roots in a cold, still house, where the soil may not dry out for three weeks. More than once I’ve been called to rescue a plant that drowned during a drought.

Water normally before you go. The answer to a long absence isn’t more water on day zero — it’s somebody delivering a normal amount of water on day five.

Problem #3: The Austin one — your trip can overlap a freeze

This is the part that only matters here, and it’s the reason I push holiday clients harder than summer ones.

Uri hit in February. The 2023 ice storm hit at the end of January. Our hard freezes land in exactly the window when people are away — Christmas through Valentine’s — and they arrive with about 48 hours of warning. If you’re in Ohio when the alert goes out, every tropical plant you own is sitting where you left it: next to an exterior window, in a house set to 60, with glass conducting cold straight into the pot all night.

You cannot fix that from a hotel room. A monstera or a calathea against cold glass at 3 a.m. is done, and you won’t know until you walk in the door a week later and the leaves have gone soft and dark. If a hard freeze is even plausible during your trip — and from December through February in Austin it always is — the plants need to be moved off the windows before you leave, not when the forecast turns. I wrote the full version of this in my Austin freeze guide; the short version is three to four feet off any exterior wall, grouped in an interior room, and up off a cold floor.

Problem #4: Forced-air heat is drier than your AC ever was

Everyone in Austin knows AC dries out a house. Far fewer people clock that running the heat is worse. Forced-air heat pulls indoor humidity down hard, and a vent blowing directly across a plant for ten days will crisp the leaf edges on anything thin-leaved even if the soil is perfectly watered.

Before a winter trip, walk the house and look at where the vents actually point. Anything sitting in the path of one gets moved. That’s a five-minute job that saves a fiddle leaf fig, and it’s free.

What actually works for a week

For a one-week trip in either season, prep alone carries most collections. Water normally. Pull everything back from the glass — south and west in summer for the sun, every exterior window in winter for the cold. Group the plants together in the brightest room that doesn’t get direct afternoon sun. Leave the blinds half-closed in July; open them in January, because winter light is weak and your plants need what little there is.

Grouped plants shade each other and hold a pocket of humidity around themselves. It costs nothing and it works.

The ten-day line

Past ten days, I’ll just say it plainly: something with hands needs to enter your house. A neighbor can absolutely do it — if you write the note. Which plants, how much, how often, and which one looks dramatic but should be ignored.

The failure mode with neighbors isn’t neglect, it’s enthusiasm. They love your plants to death in a week and a half. And in winter that enthusiasm is genuinely dangerous, because the correct winter answer for most of your plants is less water than you think, later than you think. Write the number down. Write it lower than your summer number.

One more thing worth putting in the note: what comes out of the tap here. Austin water is Colorado River and Highland Lakes surface water from the LCRA — roughly 290 mg/L hard and chloramine-treated. It’s fine for most plants most of the time, but if you’ve been filtering for your calathea or your prayer plant, your sitter has no idea, and two weeks of straight tap will show up on the leaf tips. I get into the details in my Austin hard water guide — leave them that link.

When it’s worth hiring somebody

If the trip is long, the collection is big, or the plants actually matter to you — the fiddle leaf you’ve kept alive four years, the monstera that finally split — that’s when it makes sense to bring in someone who does this for a living.

This is a real chunk of what I do, and the holidays are the busiest stretch of my year for it. Scheduled visits while you’re away, watering matched to each plant instead of a blanket soak, vents and light and window distance checked on every visit, and a photo of your plants sent to your phone afterward so you’re not wondering from a thousand miles away. If a freeze warning lands while you’re gone, I’m the one moving your plants off the glass. Every home and every trip is different, so it starts with a quick consult, not a set menu. If you’ve got a second place in the Hill Country that sits empty for stretches, same deal — I cover those too.

Two recent clients, both on short trips this summer:

“I hired Will to care for my extensive flower beds and gardens in both the front and back yards while I was away for a few days, and I’m so glad I did. … Whether your plants are indoors or outdoors, you can trust Will to know exactly how to care for them and keep them healthy while you’re away.”

— Suzanne K., Google review

“We wanted to take a short trip and I knew the plants would suffer or even die in just a day or two of this heat. Will came to the rescue! … Will did a beautiful job and all my babies were healthy and happy when we returned home!”

— Christy S., Google review

People usually want to know what it costs before anything else, so — it depends on three things: how far out you are, how many plants there are, and how often I need to come. A close-in house with a dozen plants over one week is a different number than forty plants out past Bee Cave for two. Honestly, the drive matters more than the plant count. Tell me where you are and when you’re gone and I’ll give you a straight number on the spot, not a quote that shows up three days later.

The one scheduling note: December books up. If you’re traveling between Thanksgiving and New Year’s, tell me early rather than the week before you fly.

And if you travel enough that you’d rather not think about it at all, a lot of my vacation clients end up on my regular plant watering service in Austin. Same person, same visits, whether you’re home or not.

Leave anyway

None of this is a reason to skip the trip. Plants are supposed to make your life better, not chain you to a watering can. Prep for a week, arrange hands for anything longer, move everything off the windows before a winter trip, and go.

If you want it fully off your mind, that’s what my travel and vacation watering service is for — book a free consult, or just text me at (512) 829-1467 and tell me when you fly out.

Half the people who text me from Dripping Springs open the same way: “I water it exactly like the tag said, so why does it look like that?” The tag was written for somebody in Oregon. You’re out here on Trinity Aquifer groundwater, and that one fact changes nearly everything about keeping a plant alive.

I’ve been the plant guy around Dripping Springs for years — the one neighbors call when they’ve killed three pothos in a row and are ready to admit defeat. The plants weren’t the problem. The advice was generic, and out here generic advice gets plants killed faster than anywhere in the Austin area.

Here’s what I actually pay attention to when I come to your place.

Your water out here isn’t Austin’s water

This is the one almost everybody gets wrong. Central Austin drinks treated surface water from the Colorado River. Out here, you’re on something completely different — hard Trinity Aquifer groundwater through the Dripping Springs Water Supply Corporation, and if you’re on a private well, it’s harder still and totally unregulated for the minerals that wreck houseplants.

You don’t need me to tell you the water’s under pressure. DSWSC members have been under Stage 4 restrictions since the spring of 2025, and City of Dripping Springs customers moved to Stage 2 in April 2026. Those rules are about outdoor irrigation, not your fiddle leaf — but they tell you exactly what’s coming out of your tap: hard, mineral-loaded water with no surplus behind it.

Indoors, that mineral load doesn’t evaporate. It concentrates in the pot. You get a white crust on the topsoil, chalky residue on the leaves, salt building up around the roots, and crispy brown tips that no amount of “just water it more” will fix — because more of the same water is the problem. So I pick plants that shrug it off, and I set up a watering and flushing routine built for your specific water, not a routine copied off a blog. If you want the full breakdown of how hard water hurts houseplants and what to do about it, I get into it in my Austin hard water guide.

Hill Country heat, limestone, and the AC that’s drying you out

Dripping Springs summers are their own animal. West of town the exposure is brutal, the soil is thin over limestone, and your house is sealed up running AC from May through September. That AC pulls the indoor humidity down toward desert levels, which is the part most people never connect to their plant problems.

A tropical plant that’s perfectly happy in a humid Houston bathroom will crisp at the edges in a Driftwood living room in July — not because you did anything wrong, but because the air is bone dry and the afternoon light through a west window is essentially a magnifying glass. I choose varieties that take it, place them where the light actually works, and tell you which corners to avoid. There’s more on surviving our summers in my Austin summer plant guide.

And then a freeze shows up

The Hill Country swings hard. We’ll run 105 in August and then a Uri-style freeze rolls through and the temperature falls off a cliff overnight. Tender plants near a window or on a porch don’t stand a chance if nobody’s watching. Part of what I do is text you before the cold hits and tell you exactly what to move and what to cover — I walk through the whole drill in my freeze prep guide.

What it looks like when I work with you in Dripping Springs

It starts with a free consult — I come to you, in Dripping Springs, Wimberley, Driftwood, or Henly, look at your actual light and layout, and tell you what I’d do before you spend a dollar. From there I hand-pick the plants for your water and your light, deliver and style them so the room looks intentional, and come back every couple of weeks to keep everything alive. Plants are healthy when they arrive, and if anything goes sideways in the first 30 days I replace it, no receipt and no lecture.

No contracts, no hidden fees, and you’re texting a real person who actually answers — me.

Ready to stop guessing?

Every week, somebody texts me a blurry close-up of a leaf with three words: “What is this?” After 25 years of house calls across Austin and the Hill Country, I can usually name the bug before I’ve finished reading the message — because it’s almost always one of the same five or six culprits.

Here’s what most people don’t realize: the pests you fight in an Austin home aren’t random. They’re driven by the exact conditions we live in. Our AC runs eight months out of the year, which means the air inside your house is bone dry — and dry air is a spider mite’s idea of paradise. Then people overwater trying to keep up with that dryness, and now you’ve got fungus gnats. The bugs follow the conditions.

So let me walk you through the ones I actually see in Austin homes — what they look like, where they hide, and exactly how I get rid of them. For almost all of them, my answer is the same two things, and I’ll get to that.

Pest #1: Spider Mites — The Austin Special

If I had to bet on one pest sight-unseen, it’d be spider mites, every time. They thrive in hot, dry, still air, and that describes the inside of nearly every air-conditioned Austin house from April through November. When our indoor humidity drops into the 20s and 30s during a long AC stretch, mites explode.

The tricky part is you usually can’t see the bug itself — they’re smaller than a grain of salt. What you see is the damage: a fine stippling or “dusty” speckled look across the leaf, like someone went at it with a faded pin. As it gets worse, you’ll find fine webbing tucked into the leaf joints and along the undersides. Flip the leaves over and hit them with your phone flashlight — if you see tiny moving specks, that’s them.

They go after calatheas, ivy, palms, scheffleras, and anything already stressed. In Austin, that “already stressed” part matters, because a plant fighting our hard tap water is a plant with its guard down.

One thing to flag up front, because it trips people up constantly: spider mites are the exception to my usual treatment. The systemic granules I lean on for everything else won’t touch them. Mites are a neem-oil job — and I’ll explain exactly why below.

Pest #2: Mealybugs — The Cotton Fuzz

These are easy to ID once you know them. Mealybugs look like tiny tufts of white cotton or lint wedged into the crevices where a leaf meets the stem, or buried down in fresh new growth. They move, but slowly, so people often mistake them for fuzz or mold at first.

The giveaway beyond the cotton look is stickiness — mealybugs excrete honeydew, so if the leaves below them feel tacky, you’ve found your problem. They love succulents, hoyas, orchids, and pothos, and they’re patient: they’ll hide deep in the growth point and reappear weeks after you think you’ve won.

Pest #3: Scale — The One That Hides in Plain Sight

Scale is the pest people walk past for months. It shows up as small brown or tan bumps along the stems and the undersides of leaves, and because they don’t move and look almost woody, most folks assume they’re just part of the plant.

Run a fingernail along a stem — if a “bump” scrapes off with a little wax behind it, that’s scale. Same honeydew tell as mealybugs: sticky leaves, and sometimes a black sooty mold growing on top of that stickiness. Scale loves ficus, citrus, ivy, and ferns, and it’s one of the more stubborn ones because that waxy shell shrugs off a lot of sprays.

Pest #4: Aphids — Usually a Summer-Outside Souvenir

Aphids are the soft little pear-shaped bugs that cluster on tender new growth and flower buds. Most are green, but I see black, white, and even pink ones. They reproduce fast and leave the same sticky honeydew calling card as the others.

In Austin, aphids most often show up on plants that summered outside on a porch and got carried back in for winter. If you move plants out for the warm months — and a lot of my clients do — give them a hard inspection before they come back inside, because that’s the trip where the hitchhikers get on board.

Pest #5: Thrips — The One Getting Worse

Thrips have gotten noticeably more common in the last few years, and they’re the ones that make me sigh, because they’re the hardest of this group to fully clear. They’re tiny tan or black slivers — picture an animated grain of rice, or a little comma that moves when you disturb the leaf.

You’ll often spot the damage before the bug: silvery, scratched-looking patches on the leaves and tiny black dots of frass (that’s their droppings). New leaves come in distorted, scarred, or stuck together. They fly, so they jump from plant to plant fast — which is why thrips on one plant means inspecting everything nearby. Monsteras, philodendrons, and alocasias get hit the hardest.

How I Treat Almost All of These: Neem Oil + Systemic Granules

Here’s the part I promised. For mealybugs, scale, aphids, and thrips, my treatment is the same one-two punch, and it’s worked for me for decades. Spider mites are the one exception in this group, and I’ll get to them right after.

Neem oil handles what you can see. I mix it up and spray the whole plant down — tops, undersides, leaf joints, stems, everywhere they hide — and I repeat it weekly. Neem works on contact and disrupts the bugs’ ability to feed and reproduce, so consistency is everything. A couple of Austin-specific notes I’ll save you from learning the hard way: never spray neem on a plant sitting in a hot, sunny window, and don’t do it in direct sun. The oil plus our intense light will scorch the leaves. I spray in the evening, or I move the plant out of the light first.

Systemic granules handle what you can’t. You work the granules into the top of the soil, water them in, and the plant draws the insecticide up into its own tissue. From then on, anything that bites the plant — including the eggs you missed and the bugs buried deep in new growth — gets dosed from the inside out. The houseplant systemic granules (the active ingredient is usually imidacloprid; just make sure you grab the one labeled for houseplants, not the lawn-and-garden version) are what turn this from a month-long slog into an actual fix.

Together, the neem knocks down the live population on the surface while the systemic poisons the plant from within so the next generation never gets established. That combination is how I clear infestations people have been fighting for months with spray alone.

Now, spider mites — the exception I flagged. Systemic granules will not work on them, and this is the mistake I correct most often: people dose the soil, wait a few weeks, and can’t understand why the webbing keeps spreading. The reason is that mites aren’t insects at all. They’re arachnids — closer kin to spiders than to the bugs the systemic is built to kill — so the plant can take up all the insecticide it wants and the mites won’t so much as flinch. For spider mites, neem oil is the entire program. And because they breed so fast in our dry Austin air, you have to stay on it hard: a thorough weekly spray, every surface, tops and undersides, until you’ve gone two or three weeks straight with no fresh stippling.

For the rest of the group, if you want to keep it all-natural, you can skip the systemic and run neem oil exclusively — the same way spider mites force you to anyway. But know what you’re signing up for. Neem only kills what you directly coat, so you have to be religious about it: every leaf, both sides, every week, for several weeks straight, to outlast the eggs as they hatch. It absolutely works. It just asks a lot more of you than the two-product approach does.

A few rules I follow no matter which route you take. Isolate the affected plant away from the rest of your collection the day you spot the problem. Wipe or rinse off as many bugs as you can before you treat. And be patient — pests come in waves as eggs hatch, so “looks better” on day three is not the same as “gone.” I budget three to four weeks before I’ll call something clear.

The Exception: Fungus Gnats

Now for the one pest where everything above is the wrong answer. If you’ve got little black flies bobbing around the soil and drifting up into your face, those are fungus gnats — and reaching for neem and systemics is treating the symptom instead of the cause.

In Austin, fungus gnats are almost always a watering problem in disguise. Here’s how it happens: the AC dries out the top of the pot, you see dry soil, you assume the plant is thirsty, and you water again — but down below, the soil is staying wet. That constant moisture is exactly what gnat larvae need to live and breed. Fix the moisture and you’ve fixed the gnats.

So the move is to let the soil actually dry out between waterings — the top inch or two should go bone dry before you water again. Yellow sticky traps will knock down the flying adults you already have. And if there’s an established population, a Bti product (mosquito bits or Gnatrol, watered into the soil) kills the larvae without any harsh chemicals. Bottom-watering helps too, since it keeps that top layer drier. The adults are mostly harmless to a healthy plant — but they’re a sign your watering is off, which is worth fixing for the plant’s sake anyway.

When You Can’t Tell — Or Just Don’t Want to Gamble

I’ll be honest: bug ID from a phone photo is genuinely hard, and several of these look alike until you’ve seen a few thousand of them. If you’ve flipped the leaves, hit them with the flashlight, and you still can’t tell what you’re dealing with — or it’s a plant you love and you don’t want to run experiments on it — that’s exactly what I do.

With a Keep Austin Watered Plant Rescue House Call, I come out, identify what’s actually going on, treat it on the spot, and tell you whether the rest of your collection is at risk. No contracts, no corporate runaround — just me, the same person every visit, with 25 years of knowing which Austin bug is which. Text me a photo to start and we’ll figure out whether it’s a quick fix or a house call.

Before houseplants became my whole life, I spent a stretch selling water softeners and filtration systems out here in the Hill Country. I sat at a lot of kitchen tables in Dripping Springs and Wimberley explaining what the Trinity Aquifer does to a water heater. What I didn’t understand then — and what almost nobody connects — is that the same water was quietly killing the plants on the windowsill twenty feet away.

I see it constantly now. Someone calls me out to a beautiful home on a well, the plants are struggling, and they’ve tried everything: more light, less water, new pots, new fertilizer. Nobody’s looked at the one thing every plant in the house drinks every single week — the water coming out of the tap.

If you’re on a well out here, your water is a completely different animal than what folks in town are dealing with. And if you’ve got a softener, that’s a separate problem most people never hear about until their plants are already gone. Let me walk you through both.

Problem #1: Hill Country well water isn’t Austin city water

People lump all “hard water” together, but where you are changes everything. Inside Austin, you’re drinking treated surface water from the Highland Lakes — hard, and dosed with chloramine to keep it clean through the pipes. Out here on a well, you’re pulling straight from the Trinity Aquifer through a few hundred feet of limestone, untreated. That’s a different glass of water entirely.

The good news for your plants: no chloramine to worry about. The bad news: the mineral load is heavier, and the water tends to run alkaline — high pH, packed with dissolved calcium and magnesium. You see it as the chalky white crust that forms on the soil surface and around the rim of the pot. You see it in the leaves too: high-pH water locks up iron, so a plant can be sitting in perfectly good soil and still go pale and yellow between the veins. It’s not that the iron isn’t there; it’s that the water chemistry won’t let the plant reach it. For the full breakdown of how mineral-heavy water works on plants, I’ve written that up in my Austin hard water guide — just know that on a well, you’re getting the intense, untreated version of it.

Problem #2: Your water softener is the actual plant killer

This is the one I wish every well owner out here understood, because it’s the opposite of what common sense tells you.

A standard water softener works by ion exchange. It pulls out the calcium and magnesium that scale up your pipes and water heater, and in their place it leaves sodium. That’s fantastic for your appliances, your shower, and your dishes. It is quietly lethal for a potted plant. Every grain of hardness the softener removes adds roughly 8 milligrams of sodium to each liter of water — and Hill Country well water is hard, often north of 20 grains, so the softened water coming out of your kitchen tap can carry a serious sodium load.

In the open ground, rain flushes that sodium through. In a pot, it has nowhere to go. It accumulates in the soil week after week, and sodium is a bully — it crowds out the potassium, calcium, and magnesium your plant actually needs, and it disrupts the plant’s ability to pull water up through its roots at all. The cruel part is what it looks like: scorched, browning leaf margins and tips, yellowing, stunted growth, and a plant that acts thirsty even when the soil is damp, because the salt is fooling its roots into thinking there’s no water to be had. So the owner waters more. And it gets worse. I have watched people drown plants that were actually dying of salt.

If your plants live on softened water and you’re seeing crispy edges and slow decline, the softener is the first place I’d look — not your watering can.

Problem #3: What to water with instead (the easy part)

Here’s the relief: the fixes are simple and cheap, and you don’t have to rip out your softener.

The easiest move is to water your plants from the outdoor spigot. Most homes out here have a hose bib or a line plumbed in before the softener, which means it’s still hard water — crusty, mineral-heavy, and far better for your plants than the softened water inside. It feels backwards to reach for the “bad” hard water on purpose, but for a potted plant it’s the better of the two by a mile. Even better, if you’ve got the setup, is rainwater off a downspout into a barrel: it’s naturally soft, sodium-free, and plants flat-out love it. And if you have a reverse-osmosis tap in the kitchen, that water is about as clean as it gets for pennies a gallon.

If you want to fix it at the source, swap the sodium-chloride pellets in your softener’s brine tank for potassium chloride. Potassium is a plant nutrient rather than a poison, so it takes the plant problem off the table entirely — it costs a bit more per bag, but it’s the cleanest solution for a household that wants soft water everywhere. (A salt-free conditioner does the same job without adding anything at all.)

Whatever you water with, do your pots a favor a few times a year: water heavily until it runs freely out the drainage holes, which carries accumulated salts and minerals down and out instead of letting them stack up. And when a plant looks truly worn down, repot it into fresh mix to reset the soil completely — I cover the how and when of that in my repotting guide.

If you’re not sure what your well water is doing

When I make a house call out in the Hill Country, the water is one of the very first things I check, because it’s the cause hiding behind half the “mystery” plant problems I get called about. Softener or no softener, well water out here has a personality, and once you know what it’s doing you can work with it instead of against it. (If you want hard numbers first, the Texas Well Owner Network runs low-cost well-water screenings all over the Hill Country.) If your plants are struggling and you’re on a well, that’s exactly the kind of thing I sort out — at Keep Austin Watered I diagnose it, fix the routine, and keep your plants thriving so you never have to think about the chemistry again.

Will Burke I’ve spent 25+ years keeping houseplants alive in Austin’s hard water, dry AC air, and surprise freezes. I run Keep Austin Watered, caring for indoor plants across Austin and the Hill Country.

A few weeks ago a woman in a Bee Cave high-rise told me she’d killed four plants in a single year and was officially done trying. Her place was a wall of west-facing glass, the AC ran around the clock, and she traveled for work half the month. I told her to stop trying so hard and go buy a ZZ plant.

If you’ve read my take on the snake plant, you know I don’t hand out the word “unkillable” lightly. The ZZ plant (Zamioculcas zamiifolia — nobody says that out loud) earns it. After 25+ years moving plants in and out of Austin homes and offices, it’s the one I reach for when someone swears they have a black thumb, because the exact things that kill most houseplants here are the things a ZZ is built to ignore.

And here’s what most people don’t realize: it isn’t just one boring green plant anymore. There’s a glossy near-black one, a tight compact one, a couple of cream-splashed variegated ones. You can own the toughest plant in your house and still have it look like something.

Why the ZZ Shrugs Off Austin

The secret is underground. A ZZ stores water in thick, potato-like rhizomes buried in the pot, so going two or three weeks without a drink isn’t an emergency for it — it’s just Tuesday. That single trait is why it laughs at the things that wreck other plants in this city. Our brutal summers and the bone-dry air your AC pumps out all season long quietly murder humidity-lovers; the ZZ treats that same environment like a spa day. It’s one of the rare plants where a little neglect basically is the care routine.

Problem #1: You’re Watering It Like a Normal Plant

The number one way Austinites kill a ZZ is kindness — watering it on a schedule because that’s what you do with plants. But those same rhizomes that make it drought-proof will rot fast if they sit in wet soil. Let the pot dry out completely — I mean bone dry, all the way down — then water it thoroughly and walk away. In our climate that lands somewhere around every two to three weeks, and even less in winter. If you remember one thing, make it this: when you’re not sure whether to water, don’t. And if you ever see mushy, yellowing stems, that’s overwatering, not thirst — the opposite of what most people assume. (It’s the most common mistake I see; I get into the rest of them in why houseplants die in Austin.)

Problem #2: Austin’s Hard Water Still Leaves a Mark

The ZZ is far more forgiving about our water than most plants, but it isn’t immune. Austin’s tap is hard and treated with chloramine, and over the months those minerals build up — you’ll spot it as a crusty white rim on the soil and the occasional browned leaf tip. (If you’re out in Dripping Springs pulling from aquifer water, it’s harder still.) You don’t need to fuss over it. Every few months, give the pot a big, slow flush of water to push the salts through, and pour off whatever collects in the saucer. The full story on our water and the plants that mind it least is in the Austin hard water guide.

Problem #3: You Think “Low Light” Means “No Light”

The ZZ’s real superpower is its range. It’ll happily take a bright spot set a few feet back from that west window, and it’ll also survive in a north-facing apartment corner or a windowless office where nothing else makes it. But “low-light tolerant” is not “no light.” Shove it in a truly dark corner and it won’t die — it’ll just sit there and sulk and grow almost nothing for a year. Give it even some ambient daylight and it’ll actually push out fresh stems for you.

Problem #4: It Came From a Big-Box Store in a Tired Pot

Most ZZs on the big chain racks are perfectly good plants jammed into dense peat and a flimsy pot with one weak drainage hole — which is exactly the combination that traps water against those rot-prone rhizomes. Half the “my ZZ died” stories I hear trace straight back to that setup, not the plant itself. (I get into why so many big-box store plants are built to die.) Buy from a local nursery if you can, move it into a pot with real drainage and a chunky, fast-draining mix, and you’ve removed the only genuine risk this plant has.

The Varieties Worth Hunting For

This is the fun part, and honestly it’s why I’ve been recommending the ZZ more and more lately. The standard glossy green is great, but it’s just the beginning. The Raven ZZ is the showstopper — new growth comes in bright lime and matures to a deep, almost-black green. Zenzi is a compact, tighter, curlier version that’s perfect for a shelf or a desk. The variegated ones (often sold as “Variegata” or “Lucky White”) are splashed with cream — slower-growing and pricier, but striking. And “Chameleon” / Akebono pushes out bright yellow new growth that slowly ages to green.

Heads up, though: you will not find the Raven or the variegated ones on the grocery-store rack. Those live at local nurseries and plant shops — one more reason to skip the big box. They cost more, but it’s the same indestructible plant underneath the fancy color.

One honest caveat before you fall in love: the ZZ is mildly toxic if a pet or a toddler actually chews on it — it’s the calcium oxalate, same as a lot of common houseplants — and the sap can irritate bare skin. It’s nowhere near the emergency the internet makes it out to be, but if you’ve got a determined cat or a curious one-year-old, set it up high and out of reach.

One Winter Warning

The single time a ZZ asks anything of you is during a freeze. It’s tropical — it has no business below about 45°F, and an Uri-style cold snap will turn it to mush if it’s parked next to a drafty window or sitting on a cold tile floor. When the hard freezes roll in, just move it toward the interior of the room. My full Austin freeze playbook covers what to do with the rest of your plants.

When to Call Someone

If you want the look without the learning curve — or you’ve got an office, a lobby, or a short-term rental that needs plants which stay alive between your visits — that’s exactly what we do. At Keep Austin Watered I place and maintain plants like the ZZ all over the Bee Cave, Lakeway, and Dripping Springs area, so keeping them thriving becomes someone else’s job instead of yours. Tell me about your space and I’ll point you in the right direction.
